Trying to redirect on empy...

[chadrt]

I have this line of code that reads like this:

 

$theusername = $_POST['username'];
if(empty($theusername)){
header("Location: login.php?error=allfields");
}

 

I have tried to put $_POST['username'] within the empty but either way it doesnt redirect to that it just continues to execute code in the page. The result should be back to the index.php where the login is located and then because of the error field it shows a custom message to the user.

 

No there is no other output to the browser

Yes it continues to execute code from the rest of the system

No I do not see the url in the address box of the browser showing the correct url

try this

 

$theusername = trim($_POST['username']);
if(isset($_POST['username']) && $theusername == '' ){
header("Location: login.php?error=allfields");
die();
}

or this

 

$theusername = trim($_POST['username']);
if(isset($_POST['username']) && $theusername == '' ){
die(header("Location: login.php?error=allfields"));
}

 

same thing, just one less line

That worked so much better! I have followed a few tutorials on different sites to come up what I had there and nothing worked. After looking up the "trim" at php I see how that works. Thank you!!
